DOI: 10.1016/j.engfailanal.2018.07.002
Abstract: Abstract Practically, there is multiple cracks interpenetrating in TBM cutterhead, which gives rise to its failure prematurely. While the existing theoretical formulas and calculating methods cannot calculate its fatigue failure process under dynamic loading. In… read more here.
